Getting to Know the Contenders: Samsung NX10 and Sony A6400 at a Glance

Before diving deep, let’s glance at how these cameras stack up physically and conceptually.

Key Differences

Handling and Build: Ergonomics That Shape Your Shooting Experience

Handling is about how the camera feels during use: grip comfort, control layout, and portability can all shape your workflow and enjoyment.

• Samsung NX10: As one of Samsung’s earliest mirrorless models, the NX10 offers a solid, SLR-style build typical of its time. Its fixed 3-inch OLED screen provides bright viewing, but lacks touch or articulation options. The control layout is straightforward but somewhat minimalist - reflecting its positioning toward beginners stepping up from compact cameras. Its weight (499g) and size (123x87x40mm) offer decent solidity but at the expense of some bulk. Buttons are not illuminated.

• Sony A6400: This newer rangefinder-style mirrorless camera is ergonomically refined for efficiency. It’s lighter, more compact (120x67x50mm), and features a versatile 3-inch tilting touchscreen with 922k resolution, empowering you with quick menu access and touch AF control - great for vloggers and street photographers. Physical dials and buttons are logically placed but not illuminated. The lighter weight and slick form make it highly portable for travel and street use.

My Take: You’ll appreciate the Sony A6400’s refined ergonomics and touchscreen, especially in dynamic shooting environments. The NX10's bulkier grip gives a sense of ruggedness but feels dated against the modern standard.

Sensor and Image Quality: The Heart of Your Photos

Image quality boils down to sensor technology and image processing. We relied on DXOMark scores and standardized lab tests for color depth, dynamic range, and low-light performance, paired with real-world shooting tests.

Real-World Impact

• Samsung NX10: The 15MP CMOS sensor delivers sharp, clean images with respectable color rendition and dynamic range for an entry-level camera from 2010. However, its limited ISO range caps low-light capacity, and noise becomes evident beyond ISO 1600. Landscapes and portraits shot in good light yield pleasing detail, but shadow recovery can prove challenging.

• Sony A6400: Leveraging a modern 24MP sensor with a significantly wider dynamic range and higher native ISO, this camera shines in challenging lighting. You can confidently shoot up to ISO 6400 with controlled noise, expanding creative possibilities for night photography and events. The additional pixels support larger prints and cropping flexibility without sacrificing quality.

My Advice: If you prioritize improved image quality, detailed landscapes, or low-light versatility, the A6400’s sensor is clearly superior and future-proof.

Autofocus: Precision and Speed When It Counts

Autofocus often makes or breaks a shoot, particularly for fast-moving subjects or close portraits. Our extensive testing measured AF point coverage accuracy, subject tracking, and face/eye detection reliability.

Performance Notes:

• Samsung NX10: Uses only contrast-detection AF, which is accurate but slower and prone to “hunting” in low light or fast action. Its 15-point layout covers a limited area, hampering compositional flexibility. Face detection is a helpful inclusion for portraits but lacks eye AF and real-time tracking.

• Sony A6400: Boasts an industry-leading Hybrid AF system with 425 phase and contrast points, nearly blanket coverage, and continuous real-time tracking. Eye AF (including animal eye AF) allows sharp focus on subjects’ eyes even when moving, crucial for portraiture and wildlife. Touchscreen AF boosts usability in live view.

Our Recommendation: For wildlife, sports, or fast-paced shooting, the A6400’s autofocus system is in a league of its own compared to the NX10.

Exploring Display and Viewfinder Technology

Your ability to preview and review images comfortably impacts workflow and creativity, especially in challenging light.

• Samsung NX10: Fixed OLED screen provides vibrant colors and deep contrast but limited viewing angles and no touchscreen functionality. Its electronic viewfinder (EVF) is decent but small and modest resolution, making detailed framing somewhat tricky in the field.

• Sony A6400: The standout tilting touchscreen helps you compose creative angles, vlog self-shooting, and tap-to-focus. The high-res EVF offers a clean and sharp view with natural colors and excellent magnification, vital for precision manual focusing and critical evaluation.

Pro Tip: If you often shoot outdoors in bright conditions, the Sony’s superior EVF and articulated touchscreen offer a significant advantage.

Lens Ecosystem and Compatibility: Your Creative Toolbox

Lens choice defines how versatile your system can be. A large, varied lens collection expands horizons across genres from macro to wildlife.

Insight: Sony’s E-mount has become one of the most popular and well-supported mirrorless mounts worldwide, with a huge range of native primes, zooms, and specialty lenses. In contrast, Samsung’s NX mount, now discontinued, offers far fewer options and limited third-party support.

If evolving your kit or accessing specialized glass (fast primes, super-telephoto, macro) matters, Sony is by far the better investment.

Continuous Shooting and Burst Performance for Action

Shooting sports, wildlife, or fleeting moments requires robust continuous shooting speed paired with fast AF.

The NX10’s 3 fps burst speed suits casual shooting but falls short on capturing fast action. Sony’s 11 fps burst with full AF/AE tracking allows capturing decisive moments in sequences, a game-changer for sports and wildlife.

Special Features and Video Capabilities

Both cameras offer video but differ vastly in quality and usability.

For video content creators, the A6400’s 4K recording, microphone input, and tilting touchscreen make it a compelling hybrid camera. The NX10’s HD video is basic and more suitable for snapshots or casual use.

Build Quality and Weather Sealing: Durability in the Field

If you often shoot outdoors in unpredictable conditions, Sony’s weather-sealed body and tougher construction provide peace of mind. The NX10 needs careful handling in the elements.

Battery Life and Storage

Battery life is similar but generally sufficient for day trips. The Sony’s support for UHS-I SDXC cards supports faster data writing, beneficial for 4K video.

Price to Performance: Value for Your Investment

While the Samsung NX10 is more affordable (~$626 new at launch), its legacy status means limited future support and ecosystem growth. The Sony A6400, though pricier (~$898), provides greater longevity, versatility, and capabilities, justifying its cost for serious enthusiasts.
